.SYNOPSIS... High pressure dominates and continues the dry weather pattern with well above normal temperatures across the region through Monday. A passing cold front will bring a batch of rain and possibly a storm late Tuesday into early Wednesday, followed by dry and cooler weather through Saturday.
&&
.NEAR TERM /THROUGH TUESDAY/... An expansive upper level ridge of high pressure remains firmly in place aloft, with full sunshine. At the surface, high pressure centered to the south and east of the area has placed our region in light southwest return flow. With the clear sky and very light wind, we are getting wide diurnal ranges between cool mornings and warm afternoons with highs around 15 to 20 degrees above average temperatures for this time of year.
With warm air advection continuing, temperatures will not be quite as cool as prior nights. Overnight temperatures tonight are expected to only go as low as into the mid 50s to low 60s.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/... High pressure begins to slide east and out to sea as an incoming frontal system approaches. A large upper level trough drives the system, with an embedded wave helping to push the front along and towards our area. Due to this system being a little unorganized, it`ll likely be slower in nature. PWAT values increase to up to an inch and a half with this front, with accumulating rainfall likely spanning from Tuesday morning through Wednesday afternoon. With current drought conditions, any hydrological issues such as flash flooding is not a concern. A few hundred J/kg of CAPE could bring some embedded ordinary storms as the front passes through, mainly between Tuesday afternoon and evening timeframe.
After the passage of the front with the much-welcomed rain, there will be a solid 14-18 degree drop in highs Wednesday. After upper 50s-mid 60s Wednesday, cold air advection will send temperatures to mainly 30s Wednesday night with a mostly clear sky and north-northwest wind. Some of the highest terrain area could get around freezing, and sheltered valleys also could get frost.
&&
.LONG TERM /THURSDAY THROUGH SUNDAY/... Back to dry weather for the remainder of the week, with cooler temperatures yet also fairly close to climatology.
A large high pressure will move directly over the region Thursday-Friday, and still at least be dominant even into the start of the weekend. Ideal radiational cooling set up is likely with light-calm winds and clear sky Thursday night, and thus our highest chance for areas of frost with lows of upper 20s-mid 30s; more like upper 30s near the Finger Lakes and Wyoming Valley. This of course is not at all unusual given the time of year. That will be bookended by mid 50s-lower 60s for highs Thursday, and upper 50s-mid 60s on Friday.
Many members of model ensembles depict an upper level wave or even low attempting to dig into the western Great Lakes Saturday, yet skewing south with time. Our air mass looks more likely to remain dry with surface high pressure hanging on. Thus rain chances are around or less than 10 percent during he weekend, and the National Blend of Models is around climatology with highs of 60s-near 70 and lows of mid 30s-lower 40s.

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Clear skies with widespread VFR conditions will continue the rest of this afternoon, evening and into the overnight hours. There could be some patchy fog after midnight, into the predawn hours Tuesday at ELM; bringing the possibility for intermittent IFR or lower restrictions...mainly in the 07-11z time frame Tuesday. This will be a tricky fog forecast, as skies are likely to remain clear but winds off the surface will continue out of the south-southwest up to 8-10 kts.
Mid and high level clouds increase late tonight into Tuesday morning. Eventually MVFR cloud bases and CIGs will be possible at ELM, ITH and BGM by the mid to late morning hours Tuesday as a system moves in, bringing light rain shower chances too.
Light south winds up to 10 kts will continue through sunset, and into the overnight...although some of the deeper valleys could decouple with variable or calm winds. South-southwest winds continue on Tuesday 6-15 kts.
Outlook...
Tuesday afternoon through Wednesday...Flight restrictions expected in periods of rain. SSW-NW wind shift. Gusts 20 kts.
Thursday Through Saturday...VFR. Local morning valley fog.

.BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None.
